Thisis ofconsiderable importance, as the check valve Vunder ordinary operationforms a closure for chamber Y1Q, which prevents vany oil fromenteringfthe chamber, except through the tangential openings 15. y

In operation, `as Apreviously described, it

is, foundthat the oil carbonizes'and builds upon the end loflthetiptoVsuchan vextent Vas to interfere'vvith the Voperation of the p`burnergit therefore lbecomes necessary to Y e Vremovethe 'tip' so'thatrthe carbon collected vmay ybeV removed. This is accomplished byunscrevvi'ng cap 7 andfthen vremoving the burner'tip. If the fireman'vor attendant should happen tofforget to replace the clean y c `tip korthe one just removed after it has been Cleaned, no seriousresults'willbe produced,

in the-'present instance it' the oil :should: beV

turned on,A as the pressure of the oil discharging through the centralopening'18 in the stop member 17V vvill force the ball check 13outwardly against the annular tapered shoulderl 19orm'ed interior ot thesleeve 4. The oil is thus entirely cut oil andeX- plosion or `hre of anykind prevented. The 4operator yvvill then immediately see that theburner tip has 'notwbeen replaced aiidwvill then shut oil the oilVsupply and insert the tip. Accidents of thelz'ind previously mentioned`will in this manner be avoided and theV operator willl at the same timelmoiv "that afburner tip must be inserted, as no recan be produced untilthe tip has been replaced, as the ball check Will remain on ,its seat 19until the oil under pressure is turned otl.

lIn Fig. 3 a modification has been shovvn,

`in which a check valve 20 ofthe piston type has been employed; thisvalvevis provided `with a y' plurality 'I of outwardly projecting guideymembers 21Which lform `spaces 22 through wvhich the oil is permitted toflow, exterior of the valve toenter the tangential openings 15 andchamber 10. -This typeoi' valve normally forms a closure for chamber 10,las lit also automatically seats on the tapered; seat 12 or formsgaclosure against the valve seat 19.
